Pet Deposit vs. Pet Rent: What to Charge

A prospective tenant with a good credit score and a dog just asked to see your unit, and your no-pets sign is starting to look like a vacancy problem. Before you say yes, you need to understand pet deposit vs. pet rent, because charging the wrong one — or charging both without checking your state's rules — can turn a good tenant into a fair housing complaint.

This guide walks through what each charge actually is, how much landlords are charging in 2026, which states cap or restrict pet deposits, and how to write a pet policy that protects your unit without scaring off a tenant you actually want.

Pet Deposit vs. Pet Rent vs. Pet Fee: What's the Difference

Landlords use these three terms interchangeably, but they are legally and financially different, and mixing them up is the fastest way to violate a state cap without realizing it.

Pet deposit. A refundable, one-time charge held against future pet-related damage, functionally identical to your regular security deposit. You return it, minus documented damage, after move-out — the same standard you'd apply to any security deposit deduction for damage versus normal wear and tear.

Pet fee. A one-time, non-refundable charge collected up front, separate from any deposit. Some states prohibit non-refundable pet fees outright and require all pet-related charges to be treated as a refundable deposit.

Pet rent. A recurring monthly charge added to base rent for as long as the pet lives in the unit. It is not refundable, and legally it is just rent — which means it typically is not subject to security deposit caps at all.

Each one solves a different problem. A pet deposit protects you against damage you can point to and document. Pet rent compensates you for the ongoing wear a pet adds to flooring, screens, and yards over the life of the tenancy, and it shows up as recurring income rather than a liability you're holding.

How Much Can a Landlord Charge for a Pet Deposit?

There's no single right number, but current market data gives you a starting point before you adjust for your property and local competition.

Pet rent averages $25 to $50 per month, with dogs running closer to $50 and cats closer to $35.
Pet deposits average a little over $300 nationally, with landlords in large cities charging slightly more than those in small cities.
Pet fees (the non-refundable, one-time kind, where allowed) typically fall between $150 and $300.
Roughly half of tenants with pets end up paying some form of pet charge, and pet rent has become more common than a flat deposit in many markets because it produces steady income instead of a bucket of cash you have to account for at move-out.

Run the numbers before you set a price. Add your proposed pet rent to base rent and check the total against comparable pet-friendly units nearby using Vantric's rental calculator — pricing a pet-friendly unit too high just pushes good, pet-owning tenants to your competitor down the street.

Pet Rent and Pet Deposit Laws by State

Most states don't have a law specific to pet deposits at all — they simply fold it into your regular security deposit cap, so a $300 pet deposit on top of a full security deposit can push you over the state maximum without you noticing. A handful of states go further and cap or restrict pet charges directly:

Colorado caps a pet security deposit at $300 total (not per pet) and requires it to be refundable; non-refundable pet fees stacked on top are not allowed. Pet rent is separately capped at $35 per month or 1.5% of monthly rent, whichever is greater (Colo. Rev. Stat. § 38-12-106).
Kansas limits an additional pet security deposit to half of one month's rent, on top of the standard security deposit cap (Kan. Stat. § 58-2550).
Nebraska limits a pet deposit to one-quarter of one month's rent, separate from the general security deposit (Neb. Rev. Stat. § 76-1416).
Delaware caps a pet deposit at one month's rent regardless of lease length, and it must be handled under the same return and itemization rules as a regular security deposit (Del. Code tit. 25, § 5514).
Hawaii allows an additional pet deposit of up to one month's rent, on top of the standard one-month security deposit cap, meaning a landlord there can collect up to two months' rent in combined deposits from a tenant with a pet (Haw. Rev. Stat. § 521-44).

If your state isn't on this list, that doesn't mean pets are unregulated. It means your pet deposit is governed by your general security deposit cap and refund rules, which is exactly why stacking a pet deposit on top of a full security deposit is the most common way small landlords accidentally break their state's deposit limit. Check your state's general security deposit rules at Vantric's state law hub before you set a number.

Refundable vs. Non-Refundable: What's Actually Legal

This is where landlords get tripped up most often. Many states require that any money collected as a "deposit," pet-related or not, be refundable and returned according to the same itemization and deadline rules that apply to a security deposit — regardless of whether you call it a pet deposit, a pet damage deposit, or something else.

Practically, that means a "non-refundable pet fee" is not automatically legal just because you call it a fee instead of a deposit. Some states allow a true non-refundable fee for pets as long as it's disclosed in the lease; others treat anything collected up front as a deposit no matter what you name it, and will require you to itemize and potentially return it at move-out.

Pet rent avoids this problem entirely, which is a big part of why more landlords have shifted toward charging pet rent instead of (or in addition to) a deposit. Because it's structured as recurring rent rather than a deposit, it isn't subject to security-deposit refund and itemization rules in most states. Before you write "non-refundable pet fee" into a lease, confirm your state actually allows it — if it doesn't, structure the same charge as pet rent instead.

Service Animals and ESAs: Why You Can't Charge a Pet Deposit

A service animal or a legitimate emotional support animal is not a pet under the law, and you cannot charge a pet deposit, pet fee, or pet rent for one. This applies regardless of your lease's no-pets policy, and it applies even in the states listed above that allow pet deposits for actual pets.

You can still hold the tenant responsible for real damage the animal causes beyond normal wear and tear — that gets handled through your standard move-out deductions, not a pet deposit collected up front. Where this gets genuinely complicated is figuring out which requests you're required to grant in the first place, especially after HUD's 2026 guidance change narrowed how the federal government enforces emotional support animal complaints. That shift affects federal enforcement, not your obligations under state law or the Fair Housing Act itself, so it's worth reading before you deny or waive a fee for any assistance animal request.

Writing a Pet Policy and Pet Addendum That Holds Up

A verbal "sure, bring the dog" is how landlords end up with an undocumented 90-pound animal and no way to enforce a weight limit later. Put your pet terms in a written addendum, attached to the lease, that covers:

The specific animal — name, species, breed, weight, and a current photo, so there's no dispute later about which animal is covered.
Fees and charges — the exact pet deposit, pet rent, or fee amount, and whether any portion is refundable.
Restrictions — weight limits, breed restrictions where legally permitted, and a cap on the number of pets.
A liability clause — making clear the tenant is responsible for damage and for any injury the pet causes to another person or their property.
Behavior standards and removal terms — what happens if the animal becomes a nuisance or a documented safety issue, including a cure period before removal is required.

Keep breed restrictions consistent and check your local ordinance before writing one in — some cities and counties have banned breed-specific restrictions outright, and applying one inconsistently across tenants is what turns a routine denial into a fair housing complaint.

Collecting, Documenting, and Returning Pet Money Without Disputes

Treat pet money with the same discipline you apply to a security deposit, even in states that don't legally require it:

Keep it separate and traceable. Note in your records exactly how much of what you collected is pet deposit, pet fee, or pet rent — commingling it with base rent makes it impossible to prove what you're holding if a tenant disputes a deduction later.
Photograph pet-related areas at move-in and move-out, the same way you would for a normal move-out inspection — scratched doors, stained carpet near entry points, and yard damage are the deductions tenants push back on hardest.
Follow your state's itemization and deadline rules when you return any refundable pet deposit, exactly as you would for the regular security deposit.
Track pet rent as income, not a liability, since it's taxable rental income the same way base rent is.

Vantric lets you log pet deposits, pet rent, and move-in/move-out documentation against each unit so you're not reconstructing this from a spreadsheet when a tenant moves out.
